Detailed Description

Base class for stars.

()

A Star is constructed upon (i) a mapping (derived class of Map), the center of which defines the center of the star, and (ii) an equation of state (derived class of Eos).
It contains tensor fields (class Tensor) which describe the hydrodynamical quantities as well as the gravitational field (spacetime metric).

According to the 3+1 formalism, the spacetime metric is written

$ds^2 = - N^2 dt^2 + \gamma_{ij} ( dx^i + \beta^i dt ) (dx^j + \beta^j dt )$

where $\gamma_{ij}$ is the 3-metric, described by a Lorene object of class Metric.

The 3+1 formalism introduces two kinds of privileged observers: the fluid comoving observer and the Eulerian observer, whose 4-velocity is the unit future directed normal to the t = const hypersurfaces. The hydrodynamical quantities measured by the fluid observer correspond to the members ent, nbar, ener, and press. The hydrodynamical quantities measured by the Eulerian observer correspond to the members ener_euler, s_euler, gam_euler, and u_euler.
